Mariah Carey Disses Nick Cannon in New Break-Up Track? 'Boy You Actin' So Corny Like Fritos'

The 45-year-old singer premiered her new song "Infinity" on Sunday, and its pointed lyrics are sure to get plenty of her fans talking. In the catchy new tune -- which sounds like classic '90s Mariah -- the legendary singer goes in on an ex.

"Why you mad?/Talking about you're mad?/ Could it be that you just lost the best you ever had? ... Name hold weight like kilos/ Boy you actin' so corny like Fritos/ Wouldn't have none of that without me, though," she sings right off the bat in the first verse.

Ouch.

Mariah was of course married to America's Got Talent host Nick Cannon for seven years before they split last year.

However, when ET caught up with 34-year-old Nick last month, he stressed that he could care less about negative headlines.

"You got to live life and take hardships and things like that as hurdles that were made to jump over," he told ET's Kevin Frazier. "If there's no issues within yourself or within your own family, then what other people say on the outside really doesn't matter."

"I will never say anything negative about @MariahCarey," he also tweeted in December. "We are forever a family rooted in love."
